7. Pressure-test all gas piping in accordance with local and
national plumbing and gas codes before connecting piping
to unit.
NOTE:
Pressure test the gas supply system after the gas supply
piping is connected to the gas valve. The supply piping must be
disconnected from the gas valve during the testing of the piping
systems when test pressure is in excess of 0.5 psig. Pressure test
the gas supply piping system at pressures equal to or less than 0.5
psig. The unit heating section must be isolated from the gas piping
system by closing the external main manual shutoff valve and
slightly opening the ground-joint union.
CAUTION:
Unstable operation may occur when the gas
valve and manifold assembly are forced out of position
while connecting improperly-routed rigid gas piping to
the gas valve. Use a backup wrench when making
connection to avoid strain on, or distortion of, the gas
control piping.
CAUTION:
If a flexible conductor is required or al-
lowed by the authority having jurisdiction, black iron
pipe shall be installed at the gas valve and shall extend a
minimum of 2 in. outside the unit casing.
WARNING:
Never use a match or other open flame
when checking for gas leaks. Never purge gas line into
combustion chamber. Failure to follow this warning
could result in an explosion causing serious injury or
death.
